Safety and Notices
The following topics address important safety precautions, general notes, and required RF exposure information for your mobile broadband device.
Safety Precautions
The following topics outline important safety precautions that must be observed when using your device.
Important Notice
Due to the nature of wireless communications, transmission and reception of data can never be guaranteed. Data may be delayed, corrupted (i.e., have errors) or be totally lost. Although significant delays or losses of data are rare when wireless devices such as the Sprint R850 Mobile Hotspot are used in a normal manner with a well-constructed network, your device should not be used in situations where failure to transmit or receive data could result in damage of any kind to the user or any other party, including but not limited to personal injury, death, or loss of property. Sprint accepts no responsibility for damages of any kind resulting from delays or errors in data transmitted or received using your device, or for failure of your device to transmit or receive such data.
Safety and Hazards
Do not operate your device under the following conditions. n In areas where blasting is in progress n Where explosive atmospheres may be present n Near medical equipment n Near life support equipment, or any equipment that may be susceptible to any form of radio interference
In such areas, your device MUST BE POWERED OFF. Your device can transmit signals that could interfere with this equipment.
Do not operate your device in any aircraft, whether the aircraft is on the ground or in flight. In aircraft, your device MUST BE POWERED OFF. When operating, your device can transmit signals that could interfere with various onboard systems.
Note: Some airlines may permit the use of cellular phones while the aircraft is on the ground and the door is open. Your device may be used at this time.
The driver or operator of any vehicle should not operate the device while in control of a vehicle. Doing so will detract from the driver or operator’s control and operation of that vehicle. In some jurisdictions, operating such communications devices while in control of a vehicle is an offense.
Safety and Notices

Proper Battery Use and Disposal
Follow these guidelines to ensure safe and responsible battery use. n Do not open, disassemble, puncture, crush, bend, or shred. n Do not expose to water or other liquids, fire, explosion, or other hazards. n Use the battery only in the Sprint R850 Mobile Hotspot. n If using with a charger, use only the AC charger supplied with your device. n Do not short circuit the battery. n When replacing a battery, use the same model of battery that was supplied with your device. n Follow local regulations when disposing of a used battery. n Avoid dropping your device or the battery. If dropped and you suspect damage, take it to a service center for inspection. CAUTION! Improper battery use may result in a fire, explosion, or other hazard.
FCC Compliance
This device complies with part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) This device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation.
Note: Any changes or modifications not expressly approved by the party responsible for compliance could void the user's authority to operate this equipment.
This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures:
n Reorient or relocate the receiving antenna. n Increase the separation between the equipment and receiver. n Connect the equipment into an outlet on a circuit different from that to which the receiver is connected. n Consult the dealer or an experienced radio/TV technician for help.

RF Exposure Information and Specific
Absorption Rate (SAR) Information
The following topics detail the specific absorption rate (SAR) information, electromagnetic safety information, and radiofrequency (RF) exposure information for this device.
This device is designed and manufactured not to exceed the emission limits for exposure to radio frequency (RF) energy set by the Federal Communications Commission of the United States. During SAR testing, this device is set to transmit at its highest certified power level in all tested frequency bands, and placed in positions that simulate RF exposure in usage against, and near the body with the separation of 10 mm. Although the SAR is determined at the highest certified power level, the actual SAR level of the while operating can be well below the maximum value. This is because the device is designed to operate at multiple power levels so as to use only the power required to reach the network. In general, the closer you are to a wireless base station antenna, the lower the power output. Safety and Notices 90 The exposure standard for wireless employs a unit of measurement known as the Specific Absorption Rate, or SAR. The SAR limit set by the FCC is 1.6W/kg. Tests for SAR are conducted using standard operating positions accepted by the FCC
with the device transmitting at its highest certified power level in all tested frequency
bands. The FCC has granted an Equipment Authorization for this model device with all reported SAR levels evaluated as in compliance with the FCC RF exposure guidelines. SAR information on this model device is on file with the FCC and can be found under the Display Grant section of https://www.fcc.gov/general/fcc-id-search-page after searching on FCC ID: XHG-R850
More information on the device's SAR can be found from the following FCC website: https://www.fcc.gov/general/fcc-id-search-page.
While there may be differences between the SAR levels of various devices and at various positions, they all meet the government requirement.
SAR compliance for body operation is based on a separation distance of 10 mm between the unit and the human body. Carry this device, at least 10 mm away from your body to ensure RF exposure level compliant or lower to the reported level. To support body operation, choose the belt clips or holsters, which do not contain metallic components, to maintain a separation of 10 mm between this and your body.
